A method of making coated avian egg yolk cores includes providing dried avian egg yolk cores having a diameter of 100 to 1500 micrometers, applying avian egg albumen to the dried avian egg yolk cores to provide the coated avian egg yolk cores, and optionally drying the coated avian egg yolk cores, wherein the ratio of dry avian egg albumen to dried avian egg yolk in the coated avian egg yolk cores is 1:10 to 10:1. Also included are the coated avian egg yolk cores, food and feed additives containing the coated avian egg yolk cores and food and feed compositions containing the coated avian egg yolk cores.

Neutralizing antibodies through recombinant protein expression were identified by mining antibody repertoires by high-throughput second generation sequencing. Sequencing across the majority of light and heavy chain variable regions of chicken immunoglobulins was performed at two immunological time points: a non-immune (naive) state and a post-hyperimmunization state. The mRNA was extracted from unsorted and unselected PBMC populations and identification of antigen-specific antibody sequences leveraged the significant disparity of abundance of an individual B cell clone in non-immune and immunized states. Through bioinformatic analysis, candidate amino acid sequences for variable heavy chain and light chains were identified. Recombinant polypeptides with the binding domains having the identified amino acid sequences for variable heavy chain and light chains were expressed and screened using immunoassays to confirm antigen-specificity.

Compositions and methods reduce symptoms of human allergy to cats. The effectiveness of a molecule which specifically binds to Feline domesticus allergen number 1 (Fel D1) is enhanced by prolonging the time the immunoglobulin stays within the mouth of a cat to whom the anti-Fel D1 molecule is administered in a pet food. The compositions and methods use a powder that is a dried hydrogel encapsulating the anti-Fel D1 molecule, and the hydrogel is based on gelatin, collagen peptides, or gelatin and collagen peptides; and carrageenan. The methods of making the powder provide a high encapsulation efficacy, sustained release of the anti-Fel D1 molecule in the cat's mouth, and oral adhesion of the anti-Fel D1 molecule in the cat's mouth.

Novel and effective anti-fibrosis agents are obtained. An anti-fibrosis agent containing an antagonist for integrin 81 is used. In addition, used is an antagonist containing an anti-integrin 81 antibody that specifically binds to at least one amino acid in a cap subdomain of an integrin 8 chain and a periphery thereof. Also, used is an anti-fibrosis agent containing an anti-integrin 81 antibody that specifically binds to R120 of an integrin 8 chain and a periphery thereof or S132 and a periphery thereof. Note that the above antagonists may each be an anti-integrin 81 antibody capable of binding to any of integrins 81 derived from a human, mouse, and rat.

The present invention relates to a fusion protein consisting of a scFv linked to a horseradish peroxidase enzyme or to an alkaline phosphatase enzyme by a peptide linker. The fusion protein also includes a histidine tag and optionally an endoplasmic reticulum retention signal. The invention also includes nucleic acids encoding the fusion protein, expression vectors containing the nucleic acids, plant cells transformed with the expression vectors and methods of producing the fusion proteins of the invention.

The present invention provides an ostrich antibody-containing composition for treating a bacterial infectious disease, and a method for treating a bacterial infectious disease by using the ostrich antibody. The present invention further provides a method for producing this ostrich antibody. The infectious disease can be a gastrointestinal infection. The ostrich antibody can be produced by using a component derived from a bacterium as an immunogen. The bacterium can be Clostridium difficile, Vibrio cholera, Staphylococcus aureus, or the like. Further, the bacterium can be a drug-resistant bacterium.

The present disclosure provides antibodies that specifically bind to human FAM19A5 and compositions comprising such antibodies. Also provided herein are methods for treating fibrosis or cancer using the anti-FAM19A5 antibodies.

A transgenic non-human animal is provided. In certain embodiments, the animal comprises a genome comprising an immunoglobulin heavy chain locus comprising: a) a transcribed gene encoding a fusion protein comprising, from N-terminus to C-terminus: i. a scaffold comprising a first binding domain; and ii. a heavy chain constant region operably linked to the scaffold; wherein the scaffold is capable of specifically binding to a target in the absence of additional polypeptides; and b) a plurality of pseudogenes that are operably linked to the transcribed gene and that donate, by gene conversion, nucleotide sequence to the part of the transcribed gene that encodes the binding domain.

Compounds inhibitory to Staphylococcus pseudintermedius Sortase A (SrtA) are identified. The compounds inhibit cell wall-associated protein anchoring to the bacterial cell wall, thus potentially reducing bacterial virulence.
